FIELD OF THE INVENTION

The present invention relates to a class of thiazolidinone derivatives as anandamide cellular uptake inhibitors and their use in the treatment of psychiatric or neurological disorders and inflammation, in particular neuroinflammation.

BACKGROUND OF THE INVENTION

The endocannabinoid system (ECS) is a lipid signaling system comprising endocannabinoids (ECs), which are lipids derived from arachidonic acid, the G-protein-coupled cannabinoid receptors CB1 and CB2, as well as several other actual and potential physiological targets involved in the synthesis, transport and degradation of ECs. The major ECs are 2-arachidonoylglycerol (2-AG) and N-arachidonoyl ethanolamide (AEA; anandamide) which modulate synaptic transmission by retrograde signaling via CB1 receptors and exert potent immunomodulatory effects via both CB1 and CB2 receptors. The ECS has been implicated in physiological and pathophysiological conditions including inflammation, pain, psychiatric disorders and metabolic reprogramming. The ECS provides a primary on-demand protection system against acute excitotoxicity in the central nervous system (CNS) (Marsicano et al., 2003, Science, 302, 84-8.)

Therapeutic strategies within the ECS include the use of cannabinoid receptor agonists and antagonists, blockage of hydrolytic enzymes degrading ECs, such as fatty acid amide hydrolase (FAAH) and monoacylglycerol lipase (MAGL), as well as inhibition of EC cell membrane trafficking. Although so far no membrane protein for EC transport has been identified, several lines of evidence suggest a facilitated membrane transport involving both membrane and cytoplasmic targets (Chicca et al., 2012, J Biol Chem. 287, 36944-67; Fowler C J., 2013, FEBS J., 280:1895-904). The movement of AEA across the cell is affected by the concentration gradient enhanced by rapid intracellular hydrolysis of AEA catalyzed by FAAH. Therefore, FAAH plays a key role in AEA cellular uptake by generating an inward concentration gradient for AEA, which is the major driving force for its cellular uptake.

Using the commercially available AEA uptake inhibitors UCM707, OMDM-2 and LY2183240 evidence for bidirectional transport of both AEA and 2-AG across cell membranes, as well as a common mechanism of cellular membrane transport for all arachidonate-based ECs was recently provided (Chicca et al., 2012, J Biol Chem. 287, 36944-67). Since all of the available inhibitors are only moderately potent and show low selectivity towards AEA transport inhibition over FAAH inhibition or other cytoplasmic targets, investigations of the mechanisms of AEA and 2-AG cellular uptake are hampered by a lack of adequate tools. As indicated by a recent study (Nicolussi et al., Pharmacol Res., 2014, 80:52-65), the CNS pharmacology of inhibitors of endocannabinoid breakdown and inhibitors of endocannabinoid membrane transport is distinctly different and that inhibition of FAAH and AEA cellular uptake, respectively, can be independent from each other. Prior art has shown the use of Dodeca-2E,4E-diene amides as specific AEA cellular uptake inhibitors as anti-inflammatory agents in skin (WO 2010136221 A1). The potential therapeutic value of specific AEA cellular uptake inhibitors to treat CNS related diseases remains largely unknown. In a murine model of multiple sclerosis, the AEA cell membrane transport and FAAH inhibitor UCM707 showed beneficial effects by reducing microglial activation (Ortega-Gutierrez et al., 2005, FASEB J., 19, 1338-40). Using UCM707, it was shown that an increased AEA tone limits excitotoxicity in vitro and in a model of multiple sclerosis (Loria et al., 2010, Neurobiol Dis., 37, 166-76). The non-specific AEA cellular uptake and FAAH inhibitor AM404 was shown to reduce the rewarding effects of nicotine and nicotine-induced dopamine elevations in the nucleus accumbens shell in rats (Sherma et al., Br J Pharmacol., 2012, 165, 2539-48). The non-specific AEA cell membrane transport inhibitor VDM-11 was shown to modulate sleep and c-Fos expression in the rat brain (Murillo-Rodríguez et al., Neuroscience, 2008, 157, 1-11). The administration of AEA cell membrane transport inhibitors OMDM-2 or VDM-11 was shown to promote sleep and decreases extracellular levels of dopamine in rats (Murillo-Rodríguez et al., Physiol Behav. 2013, 109, 88-95). UCM707 was shown to behave as a symptom control agent in models of Huntington's disease and multiple sclerosis, but failed to delay/arrest the progression of different motor-related disorders (de Lago et al., Eur Neuropsychopharmacol., 2006, 16, 7-18). As shown by a study using UCM707 and AM404, AEA transport inhibitors may have potential in the treatment of painful diabetic neuropathy (Hasanein and Soltani, 2009, Clin Exp Pharmacol Physiol. 36, 1127-31). Targeting fatty acid binding protein (FABP) intracellular AEA carriers has recently been suggested to be a strategy to generate anti-inflammatory and anti-nociceptive drugs (Berger et al., 2012, PLoS One., 7(12):e50968). However, the pharmacology between the inhibition of AEA cell membrane transport and the inhibition of cytoplasmic carriers is expected to be different, as exemplified by the fact that FABP5 inhibitors do apparently not show the same degree of cannabimimetic effects observed with the potent AEA cell membrane transport inhibitor guineensine (Kaczocha et al., PLoS One. 2014, 9(4):e94200; Nicolussi et al., 2014, Pharmacol Res., 80, 52-65).

Overall, there is a need for novel inhibitors of AEA cell membrane transport with superior specificity and potency to address CNS and inflammation related diseases involving aberrant endocannabinoid tone or in which AEA cellular uptake inhibition can target pathophysiological conditions. Given the fact that AEA and other endocannabinoids are involved in both synaptic processes via retrograde signaling and immunomodulatory processes, specific inhibitors of AEA cell membrane transport are expected to exert therapeutic effects in neuropsychiatric diseases involving neuroinflammation. When the degradation of AEA and other endocannabinoids is blocked, for example by covalent inhibition of FAAH, the resulting intracellular accumulation of AEA (Chicca et al., 2012, J Biol Chem., 287, 36944-67) is expected to potentially also have proinflammatory effects via oxygenation of AEA and possibly other endocannabinoids by cyclooxygenase-2 (discussed in Chicca et al, 2014, ACS Chem Biol, http://pubs.acs.org/doi/abs/10.1021/cb500177c). Therefore, the inhibition of degradation of AEA and the inhibition of cell membrane transport are distinct pharmacological interventions. Moreover, specific inhibition of AEA cell membrane transport, unlike inhibition of FAAH or cytoplasmic carriers, is expected to differentially modulate the AEA tone without leading to activation of TRPV1 channels via intracellular AEA accumulation.

Our attention, therefore, is focused on the identification of new class of molecules able to specifically inhibit AEA cellular uptake that do not affect hydrolytic enzymes, such as the serine hydrolase FAAH. We show that these compounds trigger cannabimimetic behavioral effects and inhibit inflammation, in particular neuroinflammation.

The present invention relates to thiazolidinone derivatives and their use for the treatment of psychiatric or neurological disorders and inflammation, in particular neuroinflammation. The use of the compounds of the invention in a method for treatment of psychiatric or neurological disorders is related to attenuation of neuroinflammation and neuronal retrograde signaling mediated via AEA and other endocannabinoids. In example, such diseases include multiple sclerosis, epilepsy, Alzheimers disease, bipolar diseases, schizophrenia, sleeping disorders, and spinal cord injury (Ashton and Moore, Acta Psychiatr Scand. 2011, 124, 250-61; Aso and Ferrer I, Front Pharmacol., 2014, 5, 37; Correa et al. Vitam Horm. 2009, 81, 207-30; Hofmann and Frazier, Exp Neurol. 2013, 244, 43-50; Pacher et al., Pharmacol Rev., 2006, 58, 389-462).

Examples

General Methods and Materials

Compounds and chemicals were of purest possible grade. Anandamide (AEA), (R)—N-(1-(4-hydroxyphenyl)-2-hydroxyethyl)oleamide (OMDM-2), N-(3-furanylmethyl)-(5Z,8Z,11Z,14Z)-eicosatetraenamide (UCM707), [ethanolamine-1-3H]-AEA (60 Ci/mmol) was purchased from American Radiolabeled Chemicals. Albumin from bovine serum essentially fatty acid free (BSA) (A7030), fetal bovine serum (F7524), RPMI-1640 were purchased from Sigma-Aldrich, Germany. AquaSil™ siliconizing fluid was purchased from Thermo Scientific.

[³H]-AEA Cellular Uptake

Screening for AEA cellular uptake inhibition was performed in a semi-automated procedure: Pipetting and washing steps were performed by a Biomek3000 laboratory workstation. First, required amounts of U937 cells were centrifuged at 100×g for 5 min and resuspended in RPMI (37° C.) to a final concentration of 2×10⁶ cells/mL. Then, 250 μL of cell suspension (0.5×10⁶ cells per sample) were transferred into AquaSil™ silanized glass vials (Chromacol 1.1-MTV) in 96-well format. After addition of 5 μL vehicle (DMSO) or compounds the cells were incubated at 37° C. for 15 min. As positive controls OMDM-2 and UCM707 were used at 10 μM in each run. The ETI-T compounds were measured at up to 7 concentrations in triplicates from 100 pM-100 μM. After pre-incubation, a mixture of 0.5 nM [ethanolamine-1-³H]-AEA, (60 Ci/mmol) and 99.5 nM of cold AEA (final 100 nM) was added and samples were incubated at 37° C. for another 15 min. The reaction was stopped by rapid filtration over UniFilter-96 GF/C filters (PerkinElmer) pre-soaked with PBS 0.25% BSA. Cells were washed three times with 100 μL ice-cold PBS buffer containing 1% fatty acid free BSA. After drying, 45 μL MicroScint 20 scintillation cocktail (PerkinElmer, Waltham, Mass., US) was added to the wells and the plate was sealed. Radioactivity was measured by liquid scintillation counting on a PerkinElmer Wallac Trilux MicroBeta 1450 during 2 min. Non-specific binding of [³H]AEA (100 nM) to the glass vials was never higher than 10%. IC₅₀ values were calculated by GraphPad® by non-linear regression using the built-in log(inhibitor) vs. response-variable slope (four parameters) function.

FAAH Activity

Hydrolysis of [³H]-AEA by FAAH was determined as previously described in cell homogenates of U937 cells (0.18 mg protein) (Omeir et al., 1999, Biochem Biophys Res Commun, 264, 316-20; Mor et al., 2004, J Med Chem, 47, 4998-5008). Protein amounts of cell homogenates corresponded to 0.5×10⁶ cells (U937), to assure best possible comparability of IC₅₀ values as used for the AEA cellular uptake assays. URB597 was used as positive control. Protein quantification was performed using a BCA assay (Thermo Scientific). Enzyme activity was assessed by addition of vehicle or compounds in 10 μL DMSO to 490 μL homogenate in 10 mM Tris HCl, 1 mM EDTA, 0.1% (w/v) BSA fatty acid free, pH=8 and incubation for 15 min at 37° C. After, a mixture of AEA plus [ethanolamine-1-³H]-AEA (0.5 nM) at final 100 nM was added to the homogenates and incubated for 15 min at 37° C. The reaction was stopped by addition of 1 mL ice-cold CHCl₃:MeOH (1:1) followed by vigorous vortexing. Phase separation was achieved by centrifugation at 10'000×g at 4° C. for 10 min. Radioactivity of the separated aqueous phase (upper phase) containing [³H-ethanolamine] or [³H-glycerol] was measured by liquid scintillation counting on a Tri-Carb 2100 TR liquid scintillation analyzer after addition of 3.5 mL Ultima Gold scintillation cocktail (PerkinElmer Life Sciences). Results are expressed as hydrolysis of tritium substrate in percent of vehicle treated control. IC₅₀ values were calculated by GraphPad®. Data are reported as means of n=3 independent experiments performed in triplicates.

Radioligand CB Receptor Binding

Binding properties of ETI-T compounds to hCB1 or hCB2 receptors were performed as previously reported in a [³H]-CP55,940 displacement assay (Gertsch et al., 2008, Proc Natl Acad Sci 105, 9099-104). WIN 55,212-2 was used as positive control. In brief, 20 μg protein of CHO-K1 hCB₁ or hCB₂ membrane preparations were thawed on ice and resuspended in a final volume of 500 μL binding buffer (50 mM Tris-HCl, 2.5 mM EDTA, 5 mM MgCl2, 0.5% fatty acid free BSA, pH 7.4) in silanized glass vials. [³H]-CP55,940 (168 Ci/mmol) (PerkinElmer, Waltham, Mass., US) was added to a final concentration of 0.5 nM followed by the addition of competitors or vehicle in 5 μL DMSO. Membrane binding was equilibrated for 2 h at room temperature (25° C.). Samples were filter through a 0.1% polyethylenimine pre-soaked UniFilter®-96 GF/B plate (PerkinElmer) and washed twelve times with 167 μL ice-cold assay-buffer. The plate was dried, bottom sealed and 45 μL MicroScint 20 scintillation cocktail (PerkinElmer) were added before measured on a PerkinElmer 1450 Microbeta TRILUX liquid scintillation counter. Unspecific binding was determined by WIN 55,212-2, 10 μM and subtracted from all values. IC₅₀ values.
